title: Prevalence of Toxoplasma gondii antibodies in nine populations of dairy goats: compared titers using modified direct agglutination and indirect hemagglutination.
abstract: In a convenience survey of dairy goats on 9 farms in Tennessee, Kentucky, and Georgia, 54 of 99 females were positive for antibodies to Toxoplasma gondii as measured by the indirect hemagglutination test (IHA). Two of 9 males were also positive. Positive goats were found on all farms. The percentage of positive does increased from 55% to 65% when the sera were titered a second time by modified direct agglutination (MDAT). This difference was not statistically significant, indicating that both IHA and MDAT are reliable epidemiological tools.
